THEODORE H. PRISON 31 



vox in region of antennal fossae; viewed from the front with eyes slightly 

 oblique; ocelli arranged in a triangle, lateral ocelli less than twice as far apart 

 as distance from inner margin of eye; dense, short, white setae extending from 

 cephalic margin of clypeus to half way between antennal fossae and ocelli; 

 setae about ocelli scattered, longer than those below, pale-brownish. Antennae 

 inserted about one-half length of petiole apart, far below middle of eyes; 

 scape four times as long as distance from its articulation to inner margin of 

 eye, much longer than pedicel and first flagellar segment together; pedicel 

 less than one-half as long as first flagellar segment; flagellar segments slightly 

 enlarged distad of second segment, second segment much longer than first 

 segment, first segment longer than third. 



Alitrunk nearly twice as long as broad, nearly one-third again longer than 

 high; with numerous short, pale setae, on truncature particularly dense and 

 whitish. Pronotum not forming a distinct collar on same plane as mesoscutum 

 when veiwed from above, but with neck strongly produced forward; humeral 

 angles rounded. Mesoscutum with deep parapsidal grooves, lateial grooves 

 inflicated by i)olished lines; with scattered i)unctures of moderate size an'l 

 numerous minute punctures intermixed. Mcsoscutellum se] aiated from 

 mesoscutum by a transverse suture, punctured about hke mesoscutum. 

 Metanotum narrow in center, widened somewhat laterally, coarsely punctured. 

 Propodcum above cephalad of articulation of petiole coarsely punctate, 

 l)unctures at base of petiole often confluent. Propleura wrinkled below, 

 above punctate. Mesopleura with ventral portion and anterior swelling 

 coarsely punctate; caudal half of sulcus wriid^led, a small jjolished spot in the 

 middle, cei)halic portion and area adjacent to pro])leura densely and minutely 

 liunctate. Metunapleura with cephalo-dorsal angle finely punctate; ventral 

 half with large, coarse, shallow punctures, limited above by irregular r(>ficula- 

 fions. Truncature nearly flat, with irrc^gularly subquadrate reticulations and 

 dense whitish setae. The articulation of petiole cephalad of a line vertical to 

 metacoxal fossae, the metunapleura somewhat triangular in outline. Metaster- 

 nal processes slightly divergent at distal ends. Posterior coxa reticulate above; 

 posterior tibia and posterior metatarsus with some aciculae arranged in irrc-gu- 

 lar longitudinal rows among the numerous smaller setae. Inner posterior tibial 

 spur nuich longer than outer, one-half length of posterior m(>tatarsus; posterior 

 metatarsus nearly as long as remaining tarsal segments together; tooth of claw 

 much longer and stouter than apical ray. Wings hyaline, front wings with 

 seven closed cells, subdiscoidal .-uid cubital vein in distal portion of front wing 

 not citinized and but faint l\- indicated. 



Petiole twice as long as distance from point of articulation to cepiialic 

 margin of prt)podcum, polished, with but few scattered, minute punctures. 

 Abdomen c()in])ressed, polished, triangular in outline; first four segments 

 beyond petiole bare, following two segments with dorsum and up|)er half of 

 lateral asp(>ct with dense whitisli setae, npicnl scgnient with s|);irs(' gulden 

 S(>tae.
